Fitting and use
Check the chain number and pitch of your chain against the specifications before ordering, and fit the idler on a bolt that matches the bore.
The bearing is sealed and lubricated at the factory. Keep water, grit and solvents away from the seals, and replace the idler if the bearing runs rough or noisy.
Choosing the right option
An idler sprocket must match the chain it runs on. Match the chain number and the pitch, then the number of teeth and the bore for the bolt or shaft it mounts on.
The model codes, chain numbers, pitches and dimensions for each size are in the sizes table.
